Delosperma nubigenum

[ height 4 in., flower 1" bright yellow, sun, mat former]

ICE PLANT  Another hardy South African native that is perfect for a green roof planting.  Plants have a low growing mat forming habit, with short nubby succulent foliage.  Relatively large light medium yellow flowers with radiant white centers don’t disappoint.  Plants seem to fair our winters better the more they are established.
